    The Keybase.io Verification plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.5. This is due to missing nonce validation when updating plugin settings. This makes it possible for unauthenticated attackers to update the Keybase verification text via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

    The Keybase Clients for macOS and Windows before version 5.9.0 fails to properly remove exploded messages initiated by a user.

    The Keybase Client for Windows before version 5.7.0 contains a path traversal vulnerability when checking the name of a file uploaded to a team folder. A malicious user could upload a file to a shared folder with a specially crafted file name which could allow a user to execute an application which was not intended on their host machine. If a malicious user leveraged this issue with the public folder sharing feature of the Keybase client, this could lead to remote code execution.

    Keybase Desktop Client before 5.6.0 on Windows and macOS, and before 5.6.1 on Linux, allows an attacker to obtain potentially sensitive media (such as private pictures) in the Cache and uploadtemps directories.

Local filesystem access is needed by the attacker.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
